Abstract: A safety cutting device for use in removing portions of an article from an injured person comprises a housing body and a blade, moveably coupled to the housing body. The blade has at least a spine and a cutting edge. The housing body includes an opening formed therein in which at least a portion of the blade can be stored when not in use. A safety guard is coupled to or formed integrally with a portion of the edge of the blade, the safety guard having a substantially smooth outer edge and being sized and shaped to allow the spine of the blade to safely slide along a body part of an injured person's body while restricting the cutting edge of the blade from contacting the injured person's body.

Abstract: A customizable tire chain including U-shaped members, grouser bars, and connecting segments. The U-shaped members each have a first leg, second leg, and transverse portion that extends between the first and second legs. The first and second legs are positioned to receive an outer edge portion of a tire therebetween. The connecting segments may connect the first legs, second legs, or transverse portions of the U-shaped members together. A first side of each of the grouser bars includes a traction structure. The second side of each of the grouser bars is removably coupled to the transverse portion of a corresponding one of the U-shaped members. In some embodiments, first and second ends of the grouser bars each extend laterally beyond the transverse portion of the corresponding U-shaped member. In such embodiments, the grouser bars may be coupled together at their first and second ends by the connecting segments.
